Trying to make object look like metal doesn't work
To get the effect like in the video, you have to do a few things. Firstly, arrange your nodes like I have them in the image below. You can play with the values to tweak it if you want. Secondly, the metal look in the image is the result of smooth shading and the reflection of an area light. You can see in the image, I added a square area light above the monkey, and smoothed the monkey itself by using a subdivision surface set on 2 subdivisions (ctrl+2 with monkey selected), and applying smooth shading from the right click menu. To get a basic metal look, see the settings below:

However, I see from the video that the look you're aiming to achieve is chrome, which would be better suited by this setup. Play with the ColorRamp values (even switch their positions) to change the tint - you can make it either light or dark.

You can change the color of the glossy to change the color of the object including the metallic tint. Note I accidentally connected the fresnel output of the layer weight instead of the facing output, however, you can try both and see what gives you results you like better.
